NUT-LOCK.

1,140,468, Specification of Letters Patent. Patented May 25, 1915,

Application filed FebruaryE, 1914. Serial No. 816,784. I

To all whom it may concern Be it known that I, WILLIAM F. LUD- wIoK, a citizen of the United States, residing at Beaumont, in the county of Butler and State of Kansas, have invented a new and useful Nut-Lock, of which the following is a specification.

The device forming the subject matter of this application is a nut lock and the present application discloses matter divided out of my prior application Serial No. 7 40,243 which hasnow matured into Patent No. 1,078,738.

One object of the present invention is to provide a nut lock which may be fashioned at a trifling cost from inexpensive material.

Another object of the invention is to provide a nut lock which may be employed without injuring the material in which the bolt and nut structure is mounted.

It is within the scope of the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing :Figure 1 is a perspective view illustrating a nut lock constructed in accordance with the present invention; Fig. 2 is a side elevation showing the nut lock applied to the bolt.

Referring particularly to the drawings, the nut lock herein disclosed is fashioned from a flat plate of resilient metal, slit to form a tongue 1 and to form arms 2 located along the sides of the tongue 1. The tongue 1 and the arms 2 are connected at one end by an angularly disposed primary flange 8, the arms 2 being connected at their outer ends by a secondary flange 4 disposed approximately parallel to the flange 3. The flange 3 may overhang one edge '5 of the material 6, the tongue 1 lying against one side face of the material and the arms 2 being angularly disposed with respect to the side face of the material. The flange 4 extends approximately at right angles to the side face of the material and ordinarily abuts thereagainst. The tongue 1 is provided with an opening 7, adapted to receive a bolt 8, the head of the bolt or the nut 9 thereon being held against rotation between the arms 2.

In operation, the nut 9 is rotated to a seat on the tongue 1. Then the arms 2 are bent outwardly to assume the positions shown in Figs. 1 and 2. Subsequently, the flange 4 is bent to bear against the side face of the element 6 thereby affording a support for the arms 2.

Having thus described the invention, what is claimed is In a device of the class described, a sec tion of material; a bolt and nut structure engaged therewith and including a rotatable element; and a nut lock comprising a tongue through which the bolt passes, the tongue being interposed between the rotatable element and the material, the tongue being provided with an angularly disposed primary flange engaging one edge of the material, there being arms projecting from the primary flange adjacent its ends, the arms engaging opposed edges of the rotatable element, the arms being disposed at an acute angle to the tongue, there being a secondary flange which connects the arms, the secondary flange being extended in the same general direction as the primary flange and being disposed at an angle to the plane defined by the arms, the secondary flange bearing against another edge of the rotatable element to constitute a means for preventing a rotation thereof, and bearing against the material to act as a brace for the arms,

whereby the latter will be held engaged with the first specified edges of the rotatable element.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signa:

ture in the presence of two witnesses.

WILLIAM FRANKLIN LUDWIOK.
